Sure, we have full documentation that describes all Paquet Builder features. The documentation is available online and it is also shipped with the software (can be opened directly with the Help button in Paquet Builder or by pressing F1).
Yes, we provide a deactivation facility, allowing you to transfer your license from a computer to another one. At any time, start Paquet Builder, go to the About box and choose Deactivate License. Follow instructions. If your computer is damaged, you can contact us and request a manual deactivation too.
Remember that one end user license allows you to activate your license on two computers provided that the registered user (Named User) is the only individual permitted to work with the license.
If you lost your activation code, please contact us. We require that you provide enough information for us to positively identify your purchase transaction (e.g., order number, your company name, date of transaction, number of licenses purchased, etc.).
If one day we go bankrupt, we commit to publish an offline activation key that will work on any PC, so that our customers are not blocked by our hardware locking at that time. For example, this company did that before going bankrupt: http://x2net.com/
